<P>PROBLEM TO BE SOLVED: To prevent a rotational fluctuation of an internal combustion engine and an electric motor from becoming large. <P>SOLUTION: When an absolute value of a difference between an explosion frequency Fex according to engine revolutions Ne and a rear axis side resonance frequency Fd which is a resonance frequency on a rear axis side including a damper is a threshold Fref or less (S130), a motor MG1 is controlled by setting a torque command Tm1* of the motor MG1 so that the engine revolutions Ne become target revolutions Ne* by the feed back control using gains Kp and Ki in which predetermined values Kp2 and Ki2 smaller than the values when the absolute value of the difference between the explosion frequency Fex and the rear axis side resonance frequency Fd is larger than the threshold Fref are set (S150 and S160). Accordingly, the rotational fluctuation of the engine and the motor MG1 can be prevented from becoming large, so that the vibration of the vehicle is suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
